<P>PROBLEM TO BE SOLVED: To simultaneously generate multichannel wave propagation environments in a plurality of frequency bands when evaluating reception performance of an antenna of a wireless terminal device. <P>SOLUTION: A computer 10 sets a virtual travel direction and travel speed of a reception antenna 22, calculates a maximum Doppler frequency of first wireless frequency signals, and varies phases of the first wireless frequency signals based on the maximum Doppler frequency of the first wireless frequency signals and angles of scatterer antennas 21a-1 to 21a-N so that the first wireless frequency signals radiated from the scatterer antennas 21a-1 to 21a-N become multiple waves including fading around the reception antenna 22. The computer 10 calculates a maximum Doppler frequency of second wireless frequency signals and varies phases of the second wireless frequency signals based on the maximum Doppler frequency of the second wireless frequency signals and angles of scatterer antennas 21b-1 to 21b-N so that the second wireless frequency signals radiated from the scatterer antennas 21b-1 to 21b-N become multiple waves including fading around the reception antenna 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
